RESEARCH EXPERIENCE

2017.02-present (KIGAM), Head of research team

• Standardization of structural segmentation of intraplate faults (no historical earthquake) using multiple geological approches.

• Active fault mapping, paleoseismology, and seismic hazard assessments for the Southern and Central Yangsan Fault in S. Korea based on airborne LiDAR-derived DEM

2014.10-2017.01 (IPGP), Postdoctoral Research (collaborator: Yann Klinger)

• High-resolution satellite 'Pleiades' imagery mapping, complemented by field observations, of the surface ruptures associated with the 1905 major (M ≥ 8) earthquakes in Mongolia.

• Geologic and structural controls on coseismic earthquake rupture processes, a case study for the 1905 M ≥ 8 Tsetserleg-Bulnay earthquake sequence in Mongolia.

• Impacts of fault geometry, such as fault jogs, bends, and branches, on long-term earthquake rupture scenario for strike-slip earthquakes.

2008.03-2014.08 (PKNU), Master + PhD thesis (supervisor: Young-Seog Kim)

• Geological field works focusing on deformational structures, particularly faults and fractures, at both outcrop and map scales, and interpretation of processes and history of tectonic deformations.

• Effects of fault zone structures, particularly fault damage zones, on fluid flow and earthquake rupture propagation [the Moab Fault in USA, the 1957 Gobi-Altay earthquake in Mongolia].

• Identification of active faults in Korea, based on geomorphic and paleoseismological approaches, and its implications to seismic hazard assessment [the Yangsan and Ulsan Fault System in Korea].
